An Efficient Implementation of Fixed Failure-Rate Ratio Test for GNSS Ambiguity Resolution
Sensors, 2016 Ambiguity Resolution (AR) plays a vital role in precise GNSS positioning. Correctly-fixed integer ambiguities can significantly improve the positioning solution, while incorrectly-fixed integer ambiguities can bring large positioning errors and ...

An Innovative Model of Reliability—The Pseudo-Entropic Model
Entropy, 2019 There is an entire field of literature on reliability models. Building reliability models is most frequently done by starting from the failure rate (or hazard rate). Creating a reliability model starts with the specific type of product behavior over time,

Time dependent fracture under unloading in a fiber bundle model [PDF]
, 2018 We investigate the fracture of heterogeneous materials occurring under unloading from an initial load. Based on a fiber bundle model of time dependent fracture, we show that depending on the unloading rate the system has two phases: for rapid unloading ...

Terminal Sterilization of Anterior Cruciate Ligament (ACL) Allografts: A Systematic Review of Outcomes [PDF]
, 2020 Introduction. Anterior cruciate ligament (ACL) injuries are common and reconstruction can be completed with either autograft or allograft tissue. However, there is concern about an increased failure rate with allograft tissue.

Generic approach for deriving reliability and maintenance requirements through consideration of in-context customer objectives [PDF]
, 2010 Not all implementations of reliability are equally effective at providing customer and user benefit. Random system failure with no prior warning or failure accommodation will have an immediate, usually adverse impact on operation.
